Elgar SmartWave Series High Performance AC/DC Power Source

The Elgar SmartWave™ (SW) Series of AC power sources offers powerful waveform creation for ATE and power line disturbance
simulation testing. Three separate arbitrary waveform generators enable the SmartWave to create independent, complex waveforms on all three phases simultaneously. The SmartWave is designed to meet waveform requirements including DC content (up to 312V), low distortion (THD 0.25% to 100 Hz), low noise and ripple, plus full compliance testing to many EMC and avionics standards.

At only 8-3/4 inches high for the SW 5250A, the SmartWave delivers the most power in the smallest package. The SW Series is expandable from 1.75 kVA to 22.2 kVA. Unlike other AC power sources, the SmartWave delivers full rated power to 45ºC.

Features and Benefits

Powerful Waveshape and Waveform Creation The SmartWave can easily create fractional or multicycle dropouts, spikes, surges, sags and distorted waveforms from the front panel. To simulate these complex real-world power occurrences, the SmartWave comes with a library of 50 built-in waveshapes (see examples on page 74). Users can create and store an additional 50 waveshapes of their own design. Output voltages are created by adding amplitude, frequency and other parameters to the waveshapes. The user can also create over 50 custom front panel setups with all parameters included and store them for quick recall, making the SmartWave ideal for manual testing.

Sequence Programming

Complex sequence or event programming is easy with time or cycle based transient segments. The sequence library is made up of a total of 1000 segments. A sequence of up to 100 segments using up to 32 different waveshapes, arranged in any combination, can be run at any one time. The 32 waveshapes can be selected from the 50 factory supplied and 50 user created waveshapes. By setting the time or number of cycles for each segment, the user can create waveform sequences that allow automatic testing for most any standard.

AC and/or DCA direct coupled, transformerless design allows AC and DC on separate phases or on the same phase. The SmartWave can be used as a true DC power supply. High DC content waveforms (up to 312 volts) can be created with no derating of output power, even with 100% reactive loads, eliminating the need for a separate DC supply. Waveform Programming Software (Optional) Waveform programming is easily accomplished using the optional DSP PC software. The software allows freehand creation of waveforms, using a mouse or mathematical expressions. Waveforms can be uploaded and modified from a digital scope. The waveforms can then be downloaded to the SmartWave via GPIB and output to exactly simulate real-world conditions.

Flexibility in Power Ranges

The SmartWave series includes the SW 1750/1850 (single phase only), SW 3500/3700 (single or dual phase), and SW5550. The 5250A three phase unit can be switched to single phase or vice versa, simply by menu selection (and appropriate output wiring changes). The SW Series is factory upgradable from 1750 VA to 3500 VA or 5250 VA. Utilizing a master/slave arrangement, SW5250A can be paralleled for incrementally higher power requirements, e.g. one master/one slave= SW10500 (10.5 kVA). As many as 3 slave chassis may be paralleled with a master to form a 21 kVA system. Options include input power factor correction, measurement capability, plus 5 and 26 VAC auxiliary outputs.

Waveshape LibraryThere are 50 factory-supplied waveshapes in the SmartWave. Following are examples of the types of waveshapes in the library:

  • Sine wave
  • Square wave
  • Triangle wave
  • Clipped sine waves
  • Sine waves with spikes
  • Fractional dropouts
  • Sine wave with dropout (0V from 0° to 90°)
  • Sine waves with ±1-50% DC offset
  • ±DC with 3% and 10% ripple
  • Fourier square waves with harmonics
  • Taylor series waves
  • Sine wave with noise at zero crossing
